[0002] At present, steel balls have become a relatively common basic component in transmission machinery. In existing industrial production, due to mechanical wear, steel balls often have surface damage during the production process. In addition, in many existing high-precision mechanical devices, there are strict requirements on the quality of steel balls. Because a component often uses multiple steel balls, if there is a quality error in a single steel ball, when a large number of steel balls are used, it often causes a relatively large error, causing serious mechanical wear and reducing the mechanical life.

[0003] Roundness refers to the degree to which the cross section of a workpiece is close to a theoretical circle. When the difference between the maximum radius and the minimum radius is 0, the roundness is 0. Roundness can be used as an important parameter for detecting spheres.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-6A convenient high-chromium ball shape detection device includes a base 1, which is L-shaped. Two side plates 2 are fixedly installed on the base 1. A first clamping head 3 is rotatably connected to the inner wall of one side plate 2, and a second clamping head 4 is passed through the other side plate 2. A spherical workpiece 5 is clamped between the second clamping head 4 and the first clamping head 3.

[0021] Specifically, the second clamping head 4 includes a rotating shaft 41, which rotates and passes through the side plate 2. A limit ring 42 is arranged on the rotating shaft 41. A spring 43 is sleeved on the rotating shaft 41, and the spring 43 is located between the inner side of the side plate 2 and the limit ring 42. A clamp 44 is fixedly arranged at one end of the rotating shaft 41, and a crank 45 is arranged at the other end. The inner side of the clamp 44 is spherically arranged and fits with the spherical workpiece 5, so as to clamp the spherical workpiece 5 well. When in use, the crank 45 is pulled outward to place the spherical workpiece 5 between the first clamping head 3 and the second clamping head 4, and then the crank 45 is released. Under the action of the spring 43, the spherical workpiece 5 is clamped and fixed, and the spherical workpiece 5 can be rotated by rotating the crank 45.

[0022] A detection module 6 is installed on the side wall of the base 1 , and an adjustable detection head 7 is fixedly connected to the bottom of the detection module 6 . The detection module 6 and the adjustable detection head 7 are combined to detect the roundness of the spherical workpiece 5 .

[0023] In detail, the detection module 6 includes a micrometer 61, and a connecting rod 62 is fixedly connected to the back of the micrometer 61. The connecting rod 62 is inserted into an adjustment groove 8 opened on the side wall of the base 1. A baffle 63 is fixedly provided on the connecting rod 62, and a locking nut 64 is threadedly sleeved on the connecting rod 62. By adjusting the position of the connecting rod 62 in the adjusting groove 8, the height of the micrometer 61 can be adjusted so that the detection head below is in contact with the spherical workpiece 5.
